.SPRING BED-BOTTOM.

- SPECIFICATION forming part of Letters Patent No. 624,634, dated May 9,1899.

Application filed February 25, 1898. Serial No. 671.631. (No model.)

To all whom it may concern:

Be it known that I, ROBERT J. EvERITT, a citizen ofthe United States,anda resident of New York, in the county of Kings and State of NewYork,have invented a new and useful Improvement in Spring Bed-Bottoms,of which the following is a specification.

This invention relates to certain improvements in spring bed-bottoms,the object being to provide a bed-bottom which may be easily detachedfor the purpose of cleaning, stowage, or removal, which may be easilyreplaced in its position, and in which springs may be tightened orloosened by a single operation for adjusting the bed-bottom, as may berequired.

A further object is to provide lneans for suspending the bed-bottom fromthe posts of the bedstead rather than from its end rails, as hasheretofore been usual.

A practical embodiment of my invention is represented in theaccompanying drawings, in whicl1-- Figure l represents a top plan viewof the bed bottom and bedstead, portions of the same being broken awayto more clearly show the means for suspending the bed-bottom. Fig. 2represents a side view of the same, and Fig. 3 represents a verticallongitudinal sec-- tion taken in the plane o'f the line 3 3 of Fig. l.

The portions of the bedstead herein represented consist of head-posts AA and footposts A2 A, connected by side and end rails ct a' a2 of in theusual manner. The bed-bottom proper comprises head and foot crossrails BB', connected by the springs B2, which' springs are herein representedas of the woven-wire type.

Split brackets C C' are clamped securely to the foot-posts A2 A3 atpoints a short distance above the rails of the bedstead. Each of thesebrackets comprises two members c c', secured together by bolts c2, oneof which members-in the present instance the memf ber c'-is providedwith a headed stud or pin' c3. The cross-rail B' of the bed-bottom isprovided with two eye-plates b, having elongated eyes b therein, whicheyes have enlarged and reduced portions, the enlarged portionspermitting theinsertion of the studs c3 and the reduced portions servingto engage the heads of the said studs for removably locking thecross-rail B'- to the brackets C O'.

Split brackets D D' are clamped rigidly around the head-posts A A' atpoints just above the bedstead-rails, each of the brackets comprisingtwo members d d', secured together by bolts d2. These brackets D D' areprovided with downwardly and inwardly ex tended recesses d3, openingthrough the front edges of the said brackets.

A rotary shaft E is adapted to be removably supported at its endsinbearings in the said recesses d3, one or both of the ends of the saidshaft exterior to the recesses being provided with ,a squared portion efor the engagement therewith of a wrench for use in turning the saidshaft. n for connecting the said shaft with the head cross-rail of thebottom, so as to tighten or loosen the springs by the turning of theshaft, comprise a pair of wheels having flexible connections securedthereto and to the head-rail, which iiexible connections are arranged tobe Wound and unwound on the peripheries of the said wheels. In thepresent instance I have represented these wheels as having sprockets FF' mounted in close proximity to the inner faces of the brackets D D'.The exible connections are represented as sprocket-chains `f f', adaptedto engage the teeth upon the said sprocket-wheels, the inner ei'ids ofthe saidV chains being provided with hooks f2 f3,

The means which I have shown which are removably engaged with eye-plates5 b2, carried by the head cross-bar B.

To prevent the sprocket-wheels from unwinding unintentionally, andthereby loosen the bed-bottom, I provide the shaft E with ratchet-wheelsG G', which ratchet-wheels are located between the sprocket-wheels andthe inner faces of the head-brackets D D. Gravity-pawls g g' are mountedon the inner faces of the said head-brackets with their noses inposition to engage the'teeth upon the ratchetwheels G G'. These pawlsmay be provided with thu mb-pieces g2 g3, if found desirable, for use inreleasing the pawls when it is desired to permit the sprocket-wheels tounwind-as, y for instance, when it is desired to remove the' bed-bottom.

bottom at its head portion, thehead crossrail may be provided with legsH H', which rest upon the side rails a a of the bedstead. These legs donot in any Way interfere with the tightening and loosening of thebed-bottom, as they will travel along the tops of the said rails duringthis operation. In the present instance these legs are separate piecessecured permanently to the said head crossrail at points over the siderails. By this windlass arrangement for tightening and loosening the bed-bottom the tension of the springs may be adj usted to a nicety by asingle movement, thus doing away with the necessity of adjusting anumber of bolts to produce the desired result. When it is desired toremove the bed-bottomv from the bed, the pawls are lifted away fro mengagement with their ratchets and the-shaft E is then permitted torotate, and thus loosen the flexible connections ff. The head-rail maythen be disengaged from the said iiexible connections and the foot-railmay be released from its engagement with the brackets at the foot of thebed. The bed-bottom may then be rolled up into a compact bundle.

If it is desired to remove the adjusting mechanism from the bed, theshaft E and its sprocket and ratchet wheels may be lifted out of therecesses d3 in the head-post brackets.

It is evident that the devices for removing and adjusting the bed-bottommay be reversed, and it is also evident that slight changes might beresorted to in the form and arrangement of the several parts withoutdeparting from the spirit and scope of my in- Vention. Hence I do notwish to limit myself strictly to the structure herein set forth; but

through their outer edges for the reception of the said rotary shaftwhereby7 the shaft is located on the outer side of the posts,substantially as set forth.

In testimony that I claim the foregoing as myinvention I have signedmyname, in presence of two witnesses, this 21st day of February, 1898.
